show ip ospf asbr Display all autonomous system boundary router (ASBR) routers visible to OSPF. C9000 Series Syntax Parameters show ip ospf process-id | vrf vrf-name asbr process-id vrf vrf-name Enter the OSPF Process ID to show a specific process. If no Process ID is entered, command applies only to the first OSPF process. Enter the keyword vrf and the name of the VRF to view all ASBR routers visible to the OSPF process that is tied to a specific VRF. Defaults none Command Modes ● EXEC ● EXEC Privilege Command History This guide is platform-specific. For command information about other platforms, refer to the relevant Dell Networking OS Command Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version Description 9.9(0.0) 9.4(0.0) 9.2(1.0) 8.3.19.0 8.3.11.1 8.3.7.0 7.8.1.0 7.8.1.0 7.6.1.0 7.5.1.0 Introduced on the C9010. Added support for VRF on all platforms (Except MXL and STOMP). Introduced on the Z9500. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Added support of Multi-Process OSPF. Added the process-id option, in support of Multi-Process OSPF. Introduced on the S-Series. Introduced on the C-Series and E-Series. Usage Information To isolate problems with external routes, use this command. In OSPF, external routes are calculated by adding the LSA cost to the cost of reaching the ASBR router. If an external route does not have the correct cost, use this command to determine if the path to the originating router is correct. The display output is not sorted in any order. NOTE: ASBRs that are not in directly connected areas are also displayed. Example You can determine if an ASBR is in a directly connected area (or not) by the flags. For ASBRs in a directly connected area, E flags are set. In the following example, router 1.1.1.1 is in a directly connected area since the Flag is E/-/-/. For remote ASBRs, the E flag is clear (-/-/-/).
